Measurement Response Characteristics of Array Electromagnetic Sensors

Through forward simulation and flow experimental measurement, response data of the array electromagnetic sensors is obtained to study the characteristics of electromagnetic image logging. Firstly, using finite element analysis software to establish the array sensors model and fluid distribution models and simulate measurement data, response characteristics of simulation data is analyzed. Secondly, using the electromagnetic image logging experiment instrument to obtain experimental measurement data, response characteristics of experiment data is analyzed. Finally, the similarities and differences between the characteristics of simulation and experiment data are compared. The results show that the characteristics of electromagnetic image logging response signals are closely related with the fluid distribution, so the fluid distribution can be determined by characteristics analysis.
